最近投了一篇meat science,编辑说数据分析有问题，找了一些相关文章看看，大都用randomized complete block design，但不太明白，有熟悉的童靴么，帮看看。 编辑的意见如下：There are a number of issues with this paper, but the most important is what appears to be the lack of consideration of the replicates in the analysis. It is implied line 163 that 3 independent batches of patties were prepared which is good. However replicate needs to be included as a random term in the model and the way the text reads it appears it data may have been averaged over the replicates within treatments which is incorrect. It is suggested the analysis be rethought. 为什么求重复的平均值不对呢，不都是均值±SD么。编辑还有一个意见是用SE代替SD. |

投稿的时候是这么写的：For standard calibration, three independent experiments were performed. The averages for the beef patties were calculated in duplicate for each HA. The comparison of the mean values was conducted by univariate t-test. 后面还有两个问题：It is not obvious how many samples per treatment were used, but is assumed from Table 2 that it was 2? This needs to be clearly stated earlier in the paper；Means should be given with s.e's not s.d's. |
